Thickness values are approximate and may vary slightly depending on manufacturer specifications.Brass lock nuts are hexagonal or round nuts designed to resist loosening due to vibrations, torque, and other mechanical forces. They are comúnmente utilizado en applications requiring a secure and stable fastening. These nuts are made from alta calidad brass alloys, offering superior resistencia a la corrosión, conductividad eléctrica, and durability.UsageBrass lock nuts are ampliamente utilizado en various industries due to their excellent anti-corrosion properties and ability to maintain a secure grip. Common applications include:- Electrical and Electronics – Used in electrical panels, terminals, and grounding applications due to brass’s high conductivity.
- Plumbing and Water Systems – Ideal for securing fittings in water and gas pipelines due to brass’s resistance to rust.
- Automotive and Machinery – Used in engines, gear assemblies, and vibration-prone environments.
- Marine and Aerospace – Preferred for their non-corrosive properties, making them adecuado para humid and saltwater environments.
- Construction and HVAC – Applied in heating, ventilation, and structural fastenings.
Material Grades
Brass lock nuts are manufactured using different grades of Brass alloys, which vary in composition depending on strength, machinability, and resistencia a la corrosión requirements. The most commonly used grades include:
- C36000 (Free Machining Brass) – High strength, excellent machinability, and resistencia a la corrosión.
- C37700 (Forging Brass) – Good hot-working properties, ideal for high-strength applications.
- C27200 (Yellow Brass – 63% Cu, 37% Zn) – Good resistencia a la corrosión and cost-effective.
- C46400 (Naval Brass) – Used in aplicaciones marinas due to excellent resistance to saltwater corrosion.
- C69300 (Lead-Free Silicon Brass) – Eco-friendly alternative with high mechanical strength.
Tolerance
Brass lock nuts are manufactured with high-precision tolerances, ensuring proper fitment and reliable fastening.
- Metric Tolerances – As per ISO 4035 / DIN 439, typically within ±0.1mm to ±0.3mm depending on thread size.
- Imperial Tolerances – As per ASTM B16 / ASME B18.2.2, generally within ±0.002″ to ±0.005″.
- Thread Fit – Standard threads conform to ISO 6H (metric) or 2B/3B (imperial) for a snug fit.
Surface Finish Options
Brass lock nuts están disponibles in different acabado superficiales to enhance durability, aesthetics, and performance. Common finishes include:
- Plain Brass Finish – Natural finish with a bright, metallic appearance.
- Nickel Plating – Enhances resistencia a la corrosión and provides a polished silver look.
- Chrome Plating – Improves durability and aesthetics, often used in decorative applications.
- Tin Plating – Provides enhanced conductividad eléctrica for grounding applications.
- Passivation – Chemical treatment to remove impurities and enhance resistencia a la corrosión.
- Black Oxide Coating – Reduces light reflection and enhances surface hardness.
